It’s back-to-school, and students everywhere are starting anew, hoping to make new friends while balancing classes and trying not to spill pudding on their pants during that first cafeteria lunch.

Bottom line: All of it can be scary, and it’s easy to let that self-doubt creep in.

But Old Navy is inspiring kids to be strong with its musical anthem, “Unlimited,” which encourages students to be confident, to reach for their dreams.

The back-to-school heroine Isabelle defeats her inner nemesis, the Womp Womp, which represents her nagging self-doubt.

The song was penned by Tony-nominated songwriters Benji Pasek & Justin Paul (A Christmas Story, The Musical; James and the Giant Peach, The Musical; and NBC's Smash), and the Womp Womp creature was designed by Legacy Effects, the people behind Iron Man, Captain America and The Muppets.

The idea is to entertain and engage kids on the platforms where they are naturally consuming content.

While you watch, try to spot cameos by YouTube stars, and then check out their social accounts - they’re also talking about confidence (and beating their own naysaying Womp Womps). An easy way to find the conversation is to search for #BeUnlimited. Or, go to Old Navy's YouTube channel.

Net proceeds from downloads of the song on iTunes will support the Boys & Girls Clubs of America, and creating opportunities for kids there to fulfill their unlimited potential.

For 15 years, Old Navy has supported Boys & Girls Clubs of America, and has a donation drive in stores to match customer donations up to $500,000, bringing the potential total donation to $1 million.
